It's a shame really. 140mm works perfectly fine for my needs on the rear and would have liked matching hopes but I'll put up with keeping the shimano rear caliper
What's the reason for not using Hope and 160mm? One bike I'd like to use Hope calipers on already has a fork with 'rear-style' flat mount direct for 160mm so I guess it would take a an unnecessarily huge 180mm front rotor.
Right you are, that detail had slipped passed me!
